BYD Model-Specific Maintenance Tips for New Energy Vehicles

*Leveraging BYD's proprietary technologies (Blade Battery, DM-i Super Hybrid, e-Platform 3.0, CTB, DiSus, etc.) requires tailored maintenance practices.*

🔋 1. Models with "Blade Battery" (Han EV, Tang EV, Seal, Yuan Plus, Dolphin, etc.)

• Pulse Self-Heating Optimization:

  • Prioritize BYD DC fast chargers with pulse self-heating in winter. Avoid standard fast chargers in low temperatures unless urgent.

• Battery Underbody Protection:

  • Install OEM battery guard plates if frequently driving on rough roads.

  • Reduce speed over speed bumps/potholes to prevent underbody impacts.

  • Avoid high-pressure water jets near battery seams during car washes.

• SOC Calibration:

  • Perform a full discharge/charge cycle every 3-6 months (drain to <10%, then slow-charge to 100%) to recalibrate range accuracy.

⚡️ 2. DM-i/DM-p Super Hybrid Models (Qin Plus DM-i, Song Pro/Plus DM-i, Han DM-i/p, Tang DM-i/p, Destroyer 05, Frigate 07)

• Smart SOC Strategy:

  • Highway driving: Set SOC to 50–70% + Forced Battery Maintenance for power reserve.

  • City driving: Use 25–30% SOC + Intelligent Battery Maintenance for EV priority.

• Engine Anti-Idling Protocol:

  • Run the engine monthly for 15–20 mins (via HEV driving or stationary generation) to prevent oil emulsification/fuel system issues.

  • DM-p owners: Occasionally use SPORT mode for full engine lubrication.

• EHS System Care:

  • Monitor for gearbox whining/jerking. Replace dedicated low-viscosity gear oil per manual (typically 40k–60k km).

  • After aggressive driving, engage EV mode before parking to cool motors.

🌊 3. e-Platform 3.0 Models (Dolphin, Seal, Yuan Plus, Seagull)

• • Integrated Powertrain Thermal Management:

    • Post fast-charging/performance driving, wait 2–3 mins before powering off to allow system cooling.

  • Wide-Temperature Heat Pump Efficiency:

    • Use "ECO" mode for heating in winter. In extreme cold (<-10°C), preheat cabin via app 10 mins before departure.

  • 12V Battery Failure Prevention (Dolphin/Seagull):

    • Disable parking surveillance (dashcams) during long storage.

    • Wake the vehicle weekly via app (remote AC/ventilation) to recharge the 12V battery.

    • Keep a jump starter on hand.

🏎 4. Performance & Flagship Models (Han/Tang DM-p, Yangwang U8, Denza D9)

• DM-p Warrior Edition & U8 (Tri/Quad-Motor):

  • Rotate tires every 5,000 km; monitor for uneven wear. Perform wheel alignment biannually.

  • Avoid washing immediately after track use (thermal shock warps brake discs). Shorten brake fluid intervals.

  • DiSus-P Hydraulic Suspension (U8/Tang): After storage, wait for system self-check completion before driving. Drain air tanks post-flooding.

• Denza D9 DM-i/EV:

  • Clean 2nd-row seat rails monthly; apply silicone grease (not lithium).

  • For 40+kWh packs, set daily charge limit to 90%; charge to 100% only before long trips.

🔧 5. Model-Specific Inspection Items

Insist on these during dealer service:

📌 Final Reminders: Master BYD App Features

1. Battery Health: View SOH (State of Health) for EVs or battery cycle count for hybrids.

2. Location-Based Charging: Save custom charge limits for home/work/DC stations.

3. Expert Mode (select models): Monitor real-time motor/BMS temps and cell voltages.

Pro Tip: Bookmark your model’s section and integrate these steps into regular routines. The minimal effort pays off in extended vehicle life, sustained performance, and cost savings.
